Propolis is a natural resinous substance obtained from beehives, and emerging evidence supports that it has antitumor, antiinflammatory, antioxidant, and antimicrobial activities. The aim of the study is to examine the cytotoxic, antioxidant, and apoptotic features of ethanolic propolis extract (PE) on C6 glioma cells. The cells were treated with ethanolic PE at various concentrations for 24 hours, after which the total antioxidant status (TAS) and total oxidant status; malondialdehyde, protein carbonyl, 8‐hydroxy‐2′‐deoxyguanosine, and glutathione (GSH) levels; Cu/Zn‐superoxide dismutase (Cu/Zn‐SOD) activity; and apoptotic markers were measured. Ethanolic PE at 100, 250, and 500 μg/mL concentrations showed optimal activity on C6 glioma cells. TAS and GSH levels were significantly increased in C6 glioma cells treated with 100 and 500 μg/mL PE compared to control cells (P < .05). Similarly, the activity of Cu/Zn‐SOD was higher in C6 glioma cells treated with 250 or 500 μg/mL ethanolic PE compared to control cells (P < .05), as was the caspase‐3 mRNA expression level. The highest levels of caspase‐8 and ‐9 expression were in C6 glioma cells treated with 500 μg/mL PE. Collectively, our results indicate that ethanolic PE has cytotoxic and apoptotic effects on C6 glioma cells. Furthermore, it may provide a protective role in the antioxidant defense system. PE shows potential for development as a natural antioxidant and apoptotic agent for the treatment of brain tumors.

蜂胶乙醇提取物对 C6 胶质瘤细胞的细胞毒性和凋亡作用

蜂胶是一种从蜂箱中提取的天然树脂物质,新出现的证据支持它具有抗肿瘤、抗炎、抗氧化和抗菌活性。该研究的目的是检查蜂胶乙醇提取物 (PE) 对 C6 神经胶质瘤细胞的细胞毒性、抗氧化和凋亡特征。细胞用不同浓度的乙醇PE处理24小时,然后检测总抗氧化状态(TAS)和总氧化状态;丙二醛、蛋白质羰基、8-羟基-2'-脱氧鸟苷和谷胱甘肽(GSH)水平;Cu/Zn-超氧化物歧化酶(Cu/Zn-SOD)活性;并测量凋亡标志物。100、250 和 500 μg/mL 浓度的乙醇 PE 对 C6 神经胶质瘤细胞显示出最佳活性。与对照细胞相比,用 100 和 500 μg/mL PE 处理的 C6 神经胶质瘤细胞中的 TAS 和 GSH 水平显着增加(P < .05)。同样,与对照细胞相比,用 250 或 500 μg/mL 乙醇 PE 处理的 C6 神经胶质瘤细胞中的 Cu/Zn-SOD 活性更高(P < .05),caspase-3 mRNA 表达水平也是如此。在用 500 μg/mL PE 处理的 C6 神经胶质瘤细胞中,caspase-8 和 -9 的表达水平最高。总的来说,我们的结果表明乙醇 PE 对 C6 神经胶质瘤细胞具有细胞毒性和凋亡作用。此外,它可以在抗氧化防御系统中提供保护作用。PE显示出作为治疗脑肿瘤的天然抗氧化剂和凋亡剂的发展潜力。与对照细胞相比,在用 250 或 500 μg/mL 乙醇 PE 处理的 C6 神经胶质瘤细胞中,Cu/Zn-SOD 的活性更高(P < .05),caspase-3 mRNA 表达水平也是如此。在用 500 μg/mL PE 处理的 C6 神经胶质瘤细胞中,caspase-8 和 -9 的表达水平最高。总的来说,我们的结果表明乙醇 PE 对 C6 神经胶质瘤细胞具有细胞毒性和凋亡作用。此外,它可以在抗氧化防御系统中提供保护作用。PE显示出作为治疗脑肿瘤的天然抗氧化剂和凋亡剂的发展潜力。与对照细胞相比,在用 250 或 500 μg/mL 乙醇 PE 处理的 C6 神经胶质瘤细胞中,Cu/Zn-SOD 的活性更高(P < .05),caspase-3 mRNA 表达水平也是如此。在用 500 μg/mL PE 处理的 C6 神经胶质瘤细胞中,caspase-8 和 -9 的表达水平最高。总的来说,我们的结果表明乙醇 PE 对 C6 神经胶质瘤细胞具有细胞毒性和凋亡作用。此外,它可以在抗氧化防御系统中提供保护作用。PE显示出作为治疗脑肿瘤的天然抗氧化剂和凋亡剂的发展潜力。我们的结果表明乙醇 PE 对 C6 神经胶质瘤细胞具有细胞毒性和凋亡作用。此外,它可以在抗氧化防御系统中提供保护作用。PE显示出作为治疗脑肿瘤的天然抗氧化剂和凋亡剂的发展潜力。我们的结果表明乙醇 PE 对 C6 神经胶质瘤细胞具有细胞毒性和凋亡作用。此外,它可以在抗氧化防御系统中提供保护作用。PE显示出作为治疗脑肿瘤的天然抗氧化剂和凋亡剂的发展潜力。
